For things like this I don't think you can view it as a destination, but rather a journey.

Your mind, body, and any skill will deteriorate over time if not regularly trained, so it must become a part of your life.

And because of this, the answer is easy - do what is permanently and realistically sustainable for yourself. It doesn't matter what's best when you're only going to really keep with things that are personally satisfying for yourself.
